This appears to due to the build having used the icu 4.2 headers from /usr which is given as --includedir (which should be the install directory, according to the documentation) yet for is for some reason added to the include path list,

First, you can use -sICU_PATH=/home/bgamari/OE/angstrom-dev/sysroots/armv7a-angstrom-linux- gnueabi/usr/ to specify where ICU is to be found and checked. Second, you can use -I, as opposed to -isystem, to specify headers for your sysroot, so that it is searched before -I/usr added by default value of -sICU_PATH.
The second pertains to Python. I have specified a python configuration listing the correct include and library paths in my user-config.jam yet it appears that bjam ignores it

As indicated in the documentation, I have tried passing target-os=linux/python=2.6 to bjam
What documentation is that? Although I kinda understand what this syntax is telling Boost.Build, I am totally confused as to why you might want to do that.
but this does not appear to change bjam's behavior at all. When the build process begins, bjam produces this cryptic hint,
error: No best alternative for /python_for_extensions next alternative: required properties: <python>2.6 <target-os>linux matched
Please run with --debug-configuration. This should print absolute paths to user-config.jam, site-config.jam and project-config.jam that are being loaded. Examine them to make sure only your user-config.jam configures Python. Let me know if this hlps. - Volodya
